ABA triblock copolymer comprised of poly (L-leucine) as the A segment and polyethylene glycol as the B segment was prepared by ring opening polymerisation of N-carboxyanhydride of L-leucine using the amine-terminated poly(ethylene glycol) as an initiator. Melting temperature for the gels prepared through the solution of the copolymer and chloroform was observed by inverting the test tube. The results of observation were interpreted in terms of Eldridge-Ferry plot.
